Sterizone VP4 (sterilizer)

2020: The announcement of a sterilizer of Sterizone VP4 which at the same time processes 20 respirators

In the middle of April, 2020 Stryker announced entry into the market of a new sterilizer of Sterizone VP4 intended for the used N95 respirators for the period of the outbreak of a coronavirus of COVID-19.

Sterizone VP4 uses the evaporated peroxide of hydrogen and is capable to sterilize up to 20 masks for one cycle. It is applied to processing of respirators of N95 or their equivalents for the health workers who are affected by SARS-CoV-2.

Stryker are not lonely. In March, 2020 the U.S. Department of Defense signed the contract for $415 million for delivery of 60 systems of disinfection of Battelle in which the evaporated hydrogen peroxide for deactivation of 80,000 respirators of N95 daily for the purpose of reuse is used. Steris got permission to the emergency use of own system of evaporation of peroxide of hydrogen for deactivation of respirators of N95. Similar permission was provided to the products Advanced Sterilization.

Usually respirators of N95 are intended for single use, but authors of the research published by National Institute of health defined that respirators of N95 can be deactivated effectively using any of four methods of deactivation and to maintain functional integrity to three uses. Authors of a research came to a conclusion that the evaporated peroxide of hydrogen is the most effective method of deactivation allowing to use it is more often, at the same time the virus is not detected after 10-minute processing. According to the emergency permission, Stryker allows to two cycles of deactivation on one respirator.

Such permission can be rescue for Stryker company whose core business is connected with orthopedic devices. Orthopedic transactions, as well as any planned interventions, were sharply reduced after the beginning of a pandemic of a coronavirus.^[1]
